l Letters Patent No. 102,963, dated, .May 10, 1870.

To all 'whom it may concern Be it known that we, WILLIAM-Psaumes and HENRY M. BOARDMAN, of Augustaxinthe county o'f Richmond andv State of Georgia, have' invented certain new and useful Improvements in Cotton-Presses; and

we do hereby declare the following to be a full, clear, and exact description of the construction and operation of the same, reference being had to the acco'inpa` nyingdrawings making a part of this specification, in

l which Figure 1 representsy a perspective view of the press.'

Figure 2 represents a section through the clamping `Vmechanism, consisting mainly of the rollers and inclined plane.

' Figpre 3 representsa wedge or key for raising the rollers and releasing the bnr `upon which they gripe or clamp.

Figure 4 represents in perspective the follower or moving head-block of the press, detached from the press.

Our invention consists, rst, in the -mode of griping and holding the follower-block tothe side-bars of tlie'press by means of rollers and inclined planes, asA will be explained.

And our invention further consists in using, in com- Vbination with the rollers and planes for griping, theA 'levers and links or `loops for-'operating the griping mechanism, ,as will be explained. l ;And,'nally, our invention consists in using, incom- Abiiiation with certain openings through the box or case in which the rollers work to clamp the bar, a wedge orikey" which, inpassing into said openings, raises said rollers and releases them from the bar, as ywill be explained. y

'.lo enable others skilled in the art to mak and use our invention, we, will proceed'to describe the same with reference-to the drawings.

0n thijfbase-frameA are raised the posts B, which, together-,with the;eross-pieces, bolts, and other appliances, constitute theframe of the press.

To projecting ends of t-hebecbpiece C are linked,

fas at a, or otherwisesecnred, the vertical bars 111),

which, extending upward above the top ofV the press, supporta windlass or drum, c, that may be turned by cranks, d d, and controlled by ratchets and pa-wis, as seen at 'e ,a

Tothiswindlass, drum, or rod c, is suspended, by cords or-chains, ff, the follower D, distinctly and separately shown-at iig. 4. A

The necks'g'gof the followerD move through slots or openings in theends of the press, and on the extreme outer ends of said follower, and outside of the necks g, are boxes h h, through which the upright bars b b pass, respectively, ln these-boxes are rollers i z' i i, 'a pair'n each box, and one of each of the pairs placed on opposite sides of the bars b, and so thatby the inclination of the ends jj of said bxes, the rollers will1rnn down said inclinations or planes and against said bar, passing through the box, and hold or gripe tightly said bar. A

Below the follower-boxes h h, and moving on the bars b l, are similarly-formed boxes, klc, with rollers -l 'l in them, griping said bars in a similar way as those 'in the boxes h. h. But these latter boxes and rollers are designed for a'movable fulcruin or support for the levers m m, by which .the follower is drawn down and the pressure applied to the cotton in pressing and balingbox E, which is furnished with the usual doors, links,

fastenings, 86e.

From the levers m extend links n, which hook over lugs, ears, or projections on the boxes h h, so that, by vibrating said levers, the follower is brought down, and the rollers hold it from rising. WVhen the follower is-thus brought down to wl'ere the fulcra-box and its rollers are griped onto the bars b l), then a new position inust be taken for. the boxes 7c It farther down on said bars. .Nom to release the rollers from the bar, so that they and their box can be moved, said rollers must be raised up vertically, and this, by the daring.

of the box, allows them to roll or move away from their respective bars, -and 4thus l release themselves from it. To accomplish this, openings, o o, are made in the ends of said boxes, into which a key or keys, p, lig. 3, are forced, and, as they are so forced into said openings, they take under said rollers, and', by their wedgeor tapering` form', raiseup the `rollers and release them from their bar, and then they and their boxes can be moved up or down on the bar with the greatest facility. The moment that the keys p are Withdrawn, the rollers roll'down against the bar and hold or clamp it sotight as to be immovable, except by again raising them up'as before. A When the bale is pressed, tied, and removed, and the press prepared for a new charge of cotton,`the follower is raised up by the windlass c. But before this can be done, the wedges p are inserted through the openings o, the rollers i raised, and then,l by the windlass c, the follower is readily raised up, the press recharged, and the ,pressure applied as before.l In 1ig.4 another plan of lever andlink arrangement is seen,l wherein a second. link, q, is used, into which the point of the lever m takes, while the long llink n forms a fulcrum for the lever. y The long link n hooks over the -toigue or catch s, lon the box h, while the under or shorter link q vhooks over or under the projection r on the under box k.

Having Vthus fully described our invention,

The combination of the follower-block, rollers, and inclined planes for griping and holding sziid'bloek to the side-bars, substantially :is described.

Also, in Combination with the rollers and planes for griping the side-bars, the levers and links, and their movable fulernm or support, for drawing down the block. or applying the pressure or power, substantially as described.

Also, in combination with the rollers and planes for constituting :i griping or clamping mechanism on the sidebars of a cotton-press, the Wedge or tapered keys and openings o o, for raising swirl rollers :mil releasing them from the ber, substantially as and for the purpose described.
